Question 504954
{{{ (11/8) / 3 }}}
This asks:
How do you divide {{{ 11/8 }}} into 3 equal parts?
Suppose the problem was:
How do you divide {{{ 3/8 }}} into 3 equal parts?
That would be {{{ 1/8 + 1/8 + 1/8 }}}
With your problem, you have to divide the {{{ 11 }}}
into 3 equal parts: {{{ 11/3 }}} 
Now you have {{{ (11/3) / 8 }}}
This is an important fact:
{{{ (11/8)/3 = (11/3)/8 }}}, and they both equal {{{ 11/24 }}} answer
If this is true, then {{{ 3*(11/24) = 11/8 }}}
Divide top and bottom by {{{3}}}:
{{{ (3/3)*(11/(24/3)) = 11/8 }}} OK
